Ouch.

I keep about 5% scratch in my robots, and haven't had that happen.

Granted, it'd suck.... I have seen a similar thing happen once in the last 9 or 
10 years or however long it's been and "using all the tapes" meant a bum 
DLT7000 drive mounted/failed/froze the last 4 tapes in a ATL P1000 that only 
had enough slots for that many free tapes after the backup was completed.

If you've got 3000 tapes (SL8500? Powderhorn?) in a library and you manintain a 
decent scratch ratio (better than mine) then I wouldn't lose sleep over it.
